Structural and Magnetic Properties of Nickel Ferrite Nanoparticles Synthesized by Ball Milling
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 10
Abstract
Nickel ferrite nanoparticles were synthesized by High Energy Ball milling (HEBM) of the mixture of α-NiO and α-Fe2O3 followed by annealing at 1000˚C. X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive spectroscopy (EDAX), Fourier transform infrared spectroscopy (FTIR) and Vibrating sample magnetometer (VSM) characterization of the synthesized nickel ferrite nanoparticles was performed. The structural analysis reveals the formation of the single phase compound. The average grain size was estimated by X-ray diffraction technique is 30.13 nm with the lattice constant 8.32Aº. Infrared spectra shows the presence of two strong absorption bands at 603.01 cm-1 assigned to tetrahedral and 418.65 cm-1 assigned to octahedral complex. The magnetic study at room temperature shows the saturation magnetization and coercivity for milled followed by annealing nickel ferrite nanoparticles were 36.72emu/g and 49.65 Oe. The characterization results of nickel ferrite nanoparticles shows change in the physical parameters depending on the synthesizing technique.
